The Glove Radar is a small radar that attaches to the back of any baseball. It is an inexpensive device that provides immediate feedback to help develop throwing mechanics of infielders, outfielders, and catchers, as well as pitchers. Radar "sees" through the ball glove, which is essentially transparent to the microwave energy.
Typically measures ball speed within plus or minus one mile per hour of popular "radar speed guns". Improve consistency and accuracy with less arm strain. Sealed to protect the internal electronics from dust, dirt and moisture. Operates with power from a single-cell three volt lithium battery.
Size: Triangular shape, 2 1/2" Wide x 3 1/2" Long x 1 3/16" Thick
Speed range: 20-120 MPH.
The Glove Radar is endorsed by All-Century baseball player Ken Griffey Jr.
